The introduction of the Canon PowerShot G16 brings the powerful compact camera range up to date by introducing Wi-Fi, upgrading to the latest Digic 6 processor and tweaking the autofocus for a faster response compared to its G15 predecessor.

In a world where the likes of Fujifilm is really pushing forward its X-series of large-sensor compacts - including the excellent X20 - we'd been holding out for a retort from Canon. We had a lot of love for the G15 as its images were superb, but with the G16 Canon is adding back side illumination to the sensor, which should boost it further. That new image sensor is partnered with the same 28-140mm lens wrapped up in the same body size as before.

Much of that should mean great things. With the BSI 12.1-megapixel 1/1.7-inch image sensor at its core it's got a good baseline to work from, and the Digic 6 processor on board means there's scope for yet further improved image quality in the latest PowerShot. Add the wide aperture - which maxes out at f/1.8 at the wide-angle and f/2.8 at the top-end of the zoom - and there's plenty of creative control too. That's what the G-series is all about.

The headline feature is the G16's "41 per cent" - don't forget the all-important one, folks - improved autofocus speed. We can't verify this as yet, having not seen the camera in use, but it sounds like a positive push forward.

Speed is apparently abundant elsewhere too: with the first five frames captured at 12fps, then upwards of nine frames per second (9.3fps is the full figure) until the card is full, giving burst shooting plenty of muscle to flex.

Elsewhere 1080p movie capture is available at 50 or 60 frames per second, while a new "Star Mode" is said to show off the camera's low-light capabilities.

Available in October, the Canon PowerShot G16 will be priced at £529 - the very same RRP as its predecessor at launch.
